Flu vaccination increases risk of flu in following seasons?

A double-blind, placebo-controlled study suggests that vaccination with seasonal influenza vaccine did, in fact, worsen symptoms after subsequent exposure to H1N1 flu.

The study
Even though this study was presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy and is considered to be preliminary until published in a peer-reviewed journal, it still makes for interesting reading.

“We did find that the ferret findings were consistent with our earlier human studies” said Danuta Skowronski, MD, a fellow in epidemiology at the University of British Columbia in Vancouver.  Ferrets are considered to be excellent models of human influenza infection.  Please note: I do not support animal testing in any way at all, I am merely reporting on the research.
